Abstract
An inkjet printer for printing a print paper (3) by ejecting a UV-curing type ink through an inkjet print head (5) incorporates an ultraviolet irradiation device (A) for irradiating the ultraviolet light to a target ink position following the ejection of the UV-curing type ink. The device (A) has an ultraviolet light generator (10) for generating the ultraviolet light and optical fibers (11a, 11b) through which the ultraviolet light is guided to a position close to the inkjet print head (5). The ultraviolet light is irradiated through tips of the optical fibers (11a, 11b) in order to cure the UV-curing type ink.
Claims20
An inkjet printer having an inkjet print head through which a photo-curing type ink is ejected onto a print media in a printing process, comprising:
- a photo-irradiation device irradiating a beam of light to a target ink position on the print media onto which the photo-curing type ink has been ejected following the ejection of the photo-curing type ink through the inkjet print head.
An ink curing method of an inkjet printer having an inkjet print head comprising:
- ejecting a photo-curing type ink on a print media through the inkjet print head;
- irradiating a beam of light by a photo-irradiation device to a target ink position on the print media onto which the photo-curing type ink has been ejected by the photo-irradiation device immediately following the ejection of the photo-curing type ink in order to cure the photo-curing type ink at the target ink position on the print media.
